Egg-xact Timing is a sidequest available in Fossil Fighters: Champions. To do this quest, the player must go to the hot spring in Hot Spring Heights and talk to the man near the edge of the water, named Gregg Cooke. Cooke will ask the player to time him while he boils an egg in the water. If the player successfully times Cooke for 10 seconds, he/she wil receive a Miraculous Fossil Rock, but only upon the first completion. Beating this challenge again only nets the player a Dark Giant Fossil Rock containing Dropping Fossils.
